er LO INVENTOR. RUDOLPH D. MORRONE ATTORNE United States Patent 3,260,160 THREE DIMENSIONAL DUPLICATING MACHINE Rudolph D. Morrone, 2120 Chapel Ave., Cherry Hill, NJ. Filed Feb. 25, 1965, Ser. No. 435,217 1 Claim. (Cl. 9013.1)

My invention relates to a three dimensional duplicating machine especially adapted for use in mechanical dental laboratories and similar establishments.

In a dental laboratory for example, it is often necessary to make an exact duplicate of a tooth, or a denture, or a part thereof, and it is the purpose of this invention to produce an improved machine for the purpose set forth.

The full nature of the invention will be understood from the following specification and the accompanying drawings in which:

FIGURE 1 is a perspective view of a machine embodying the invention.

FIG. 2 is a top plan view of the same.

FIGS. 3, 4 and are sectional views looking in the direction of line 3-3, 44, and 5-5 on FIG. 2.

FIG. 6 is a sectional view looking in the direction of line 66 on FIG. 4.

The duplicating machine illustrated includes a generally L-shaped, main supporting frame 10 Which is formed of a horizontal base 12 and a vertical wall 14 which rises from, and extends longitudinally of base 10 as shown in FIG. 1. Base 12 and vertical wall 14, are of substantial weight and thickness so as to afford the necessary strength and stability.

Wall 14 supports an angle 16 which is adapted to support a matrix 18, or the piece to be duplicated, and the work piece 20 which is to be a duplicate of the matrix. The matrix and the work piece may be adjustably secured to the vertical, or to the horizontal, wall of angle 16 by any suitable means not shown.

Wall 14 also carries upper and lower guide rods 22 and 24 on which vertical slides 26 and 28 are freely movable in the direction of the double headed arrow 30.

Slides 26 and 28 carry upper and lower shafts 32 and 34 on which upper and lower slides 36 and 38 are movable in the direction of double headed arrow 40. For best results, slides 36 and 40 are provided with ball bearings 42.

Slides 36 and 38 are secured to the upper and lower ends of a center plate 44 which is provided with a vertical slot 46 for receiving bolts 48 which are freely movable in said slot in the direction of double headed arrow 50.

Bolts 48 also pass through outer assembly plates 52, through ball bearing members 54 which slide against plate 44 on either side of slot 46, and through a bracket 56 to secure said bracket, said ball bearings and said Patented July 12, 1966 ice plates together to form a carriage assembly. Bracket 56 is bent to form an upper platform. 58 to which a follower 60 is suitably secured by a clamp vise 62 which is tightened by wing nut 64, FIGS. 1 and 5.

Bracket 56 also carries a lug, or extension 66 which has an opening 68 for snugly receiving the conical nose of a drill or other cutting tool 70.

The operation is as follows:

The matrix 18 and the work piece 20 are clamped in identically indexed positions on angle 16; follower 60 is clamped to platform 58 of bracket 60, and drill 70 is placed in position as shown in FIG. 1. To cut horizontally, or in the direction of the axis of the drill, blocks 26 and 28 are moved in the direction of arrow 30. To cut transversely of the axis of the drill, the assembly carried by bolts is moved as indicated by arrow 40, and to cut up and down, or to vertically adjust the drill, the assembly referred to is moved relative to plates 52, in the direction of arrow 50.

It will be seen that with follower 60 in constant engagement with matrix 18, the application of the cutter 70 to the work piece will produce a contour which is exactly identical with that of the matrix.

What I claim is:

A three dimensional duplicating machine including:

a horizontal base and a vertical wall coacting to form a supporting frame,

means carried by said wall for supporting a matrix and a work piece in identical side by side positions,

a first set of guide rods projecting from said wall and overlying said base,

a first pair of vertical slides movable on said first set of guide rods toward, and away from, said matrix and said work piece,

a second set of guide rods carried by said first pair of slides and disposed parallel to said base and to said wall,

a carriage assembly movable on said second set of guide rods toward either of said vertical slides and parallel to a vertical plane passing through said matrix and said work piece,

a vertically fixed supporting plate forming part of said carriage,

a bracket,

means mounting said bracket for vertical movement relative to said carriage,

means clamping a follower and a cutting tool to the upper end of said bracket.
